if the 2 parts missing for 3sp (SEEN LOTS OF CARS WITH MIXED PARTS , X10 THIS OLD) Old cars have this bad habit of missing parts or mixing AT parts with MT engine. or reverse. the A/T intake manifold has 1 more vacuum port nipple.
1:; vacuum nipple for vacuum modulator hose to 3sp box.
2:: that silly TB base heater not there
then see is 100% 5 speed if ECU shows MT LOGO ON ECU LABEL.
HOT START BAD, Well of you have huge vacuum leak the engine inject for no leak and goes lean.
find the vacuum leak first, this is serious issue,
after cranking cycle ends the ecu ENDS THAT MODE AND GOES TO RUN MODE AND ENDS LEAN. (MAP WAKES UP)
